International Tax Review is publishing its second annual guide to the world’s leading specialists in tax controversy. Find out if you have been included.

The need for advice from professionals with expertise in tax disputes is more important than ever as governments and tax authorities are becoming more aggressive in their search for revenue. In this type of environment, where all deals are facing increased scrutiny, it is crucial that taxpayers have access to practitioners with experience in all stages of tax controversy, including pre-audit, audit, administrative appeals, and litigation. Taxpayers will need advice from lawyers and advisers that have experience across a number of venues. The litigators in this guide will have experience not only at every level of the courts, but also in administrative proceedings, audits, appeals, and competent authority negotiations.

The practitioners listed will also have skills that extend beyond the courtroom. They also have experience in pre-trial matters including responding to third-party requests for information and summonses for tax accrual workpapers and other privileged documents. They are also familiar with document collection and analysis and preparation of expert testimony and reports, all of which can be invaluable when preparing to litigate.

The guide also includes experts in the mediation and arbitration of tax disputes, a process that is becoming increasingly common among governments, courts and regulatory agencies.

Inclusion in the guide is based on a minimum number of nominations received from peers and clients, along with evidence of outstanding success in the last year. Firms and individuals cannot pay to be recommended in the guide.
